TO ALL WHOM IT MAY CONCERN:V

Be it known that I, WILLIAM PIcKnNs, of Chicago, inthe county ofCook,and State of Illinois, have invented an Improved Bolt-.Feeder andCooler," and do hereby declare that the following Ais a full and exactdescription thereof, reference being had to' the accompanying drawings,making part of this specification, in whichi A 1 Figure 1 is a verticalsection of the whole apparatus, and

Figure 2 is a plan ofthe same on the line :s y.

i The nature of my invention consists in conveying feed from the coolerof the mill through a cylindrical case of telescopic construction,inside of which revolves a spindle, provided with breakers and fans, thefirst to workup and loosen the feed, and the second to produce a draughtof air by means of the.ventilating-casesurrounding the base of theconveying-case, and thereby cool the feed and force it from thereceivingcase into the spout through which the feed goes into the bolt,as will be hereinafter fully described.

To enable others skilled in the art to make and use my invention, I willproceed to describe its construction and operation. v 4

A and B are the sections of the cylindrical case N, made of sheet iron,B overlapping A in a telescopic manner, and slid up and down by means oflever C, pivoted at D, andworked by rod E, 4or by some other equivalentmeans. F is a saucer, made of cast iron, and of a semi-spheroidal shape,firmly set ou the spindle G,lby means of which', and by raising ,orlowering case B, the admittance of'feed into the bolt is regulated. H Hare the breakers, set firmly onthe spindle G, to work up and loosen thefeed as it is passingjdownfrom the cooler. I is Ventilating-case, madeof tin, and provided with openings cl d and sldesff, to admit air andregulate the draught. K K are the fans secured to the spindle G, toproduce a draught through the openings dd into the receiving-case L andforce the same into the spout M, thus conveying the feed through thesame into the bolt. The case A is secured to the door O of the cooler,the Ventilating and the receiving-cases are secured to the centre-boardP, and the spout goes through the lower board Q, thus conveying feedright into the bolt. Spindle C is provided with a. bevel-pinion at thelower end, and is Worked by the gear woxding the bolt.

The advantage of this arrangement is, that the feeding ofthe bolt is notintermittent, as in other devices of this kind, but is steady, owing,and uniform all the time; besides, sticks or iron, or any otherobjectthat happens to getinte the cooler, cannot be4 conveyed to the bolt andinjure cloth, butgvill be'retained in thecase N during the operation. Ii l l What I claim as my invention, and desire to secure by LettersPatent, is-

Spindle G, with saucer F, breakers H H, and 4fans K K, secured to it,and constructed as' described, in

combination with conveying-case N and Ventilating-case L'bothconstructed as described, the whole arranged and operating substantiallyas and in the manner herein set forth, and for the purpose specified.
